HIM digital and analog electronic sensors

A sensor (sentire of latin, dt. "Feel" or "feeling"), also alsDetektor, (Messgrößen- or measuring) sensor or (measuring) called sensor is a technical component that certain physical or chemical properties (eg physico . B. amount of heat, temperature, humidity, pressure, sound field sizes, brightness, acceleration or chemically z. B. pH, ionic strength, electrochemical potential) and / or the physical condition of its environment can quantitatively or qualitatively as a benchmark. These variables are recorded by means of physical or chemical effects and transformed into a processable electrical signal.

For metrology 1319-1 the term sensor (measured variables pickup) is used and is defined as the part of a measuring device, which directly responds to a measure in DIN. Thus, the sensor is a measuring chain, the first element. According to DIN 1319-2, the pickup is one of the transmitters, with the same physical size of the input and output also to the transducers.

The distinction between the terms and Transducers Sensor, sensor, gauge, measuring equipment etc. is fluid because the sensor can be assigned in addition to the actual sensor may include additional elements of the measurement chain. Also related terms are not clearly defined in the literature.
